e9d7210d02 sim/posix_test: fix shm_open() return file descriptor associated with FD_CLOEXEC
Make the pthread_setspecific pass the shm_open/11-1.c testcases. Function shm_open() should return a file descriptor for the shared memory object associated with FD_CLOEXEC. Reference to https://pubs.opengroup.org/onlinepubs/9699919799/functions/shm_open.html and https://github.com/lattera/glibc/blob/master/sysdeps/posix/shm_open.c#LL38C1-L38C1

6ee9ec7656 build: add initial cmake build system
1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)

------------------

How to test

From within nuttx/. Configure:

cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja

(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja

This uses ninja generator (install with sudo apt install ninja-build). To build:

$ cmake --build build

menuconfig:

$ cmake --build build -t menuconfig

--------------------------

2. cmake/build: reformat the cmake style by cmake-format

https://github.com/cheshirekow/cmake_format

$ pip install cmakelang

$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

53d4b9ed54 mm/mm_map: Give the mm_map as parameter to the mm_map functions
This way the mappings can be modified for any vm area, not only the
process that is running.

Why? This allows mapping pages to kernel dynamically, this functionality
will be presented later.

a0ebddaac1 fs/shm: Add initial implementation for posix shared memory
This implements the file system logic for posix shared memory:
shm_open, shm_unlink, mmap, munmap and close

For flat and protected builds the memory simply allocated from (user) heap

For kernel build the memory is allocated from page pool and mapped with MMU

This doesn't yet support protection flags or re-sizing already truncated shared
memory area.
